Not enough time: At this point, you would have to wait until your next period to be able to determine if you are pregnant. If you took the morning after pill as prescribed, your likelihood of being pregnant is low. If your next period is late, you will need to take a pregnancy test. Take care.

Pregnancy unlikely: Most likely the medication (if high dose progesterone) you took would prevent pregnancy. If you do not get your period at the end of the month, do a home pregnancy test with the first urination of the morning. Consider talking to your doctor about a second form of birth control and continue to use condoms as well.
